I have some cals mixes and some pure .. most of them are 6.5 pounds and born June 1st.. but to me that isn't good enough.. should I put them in the freezer.? I do have a very good body type and big purebred cal to breed with them to bring up the weight.. well, Hoping to... He is 8 pounds and is 5 months old. I also have a show quality nz doe.. she is only 5 pounds at 4 months old. .. then I have the same lines but they are adult.. 11 and 12 pounds.. they are sure slower to grow .. but nice when it comes to adult size.. I don't know what to do
